3 2 safety rules regarding outdoor power equipment IMPORTANT! READ CAREFULLY THE FOLLOWING SAFETY RULES BEFORE ASSEMBLING OR OPERATING UNIT. TRAINING Read, understand, and follow all instructions in the manual and on the unit before starting. If the operator(s) or mechanic(s) can not read English it is the owner s responsibility to explain this material to them. Become familiar with the safe operation of the equipment, operator controls, and safety signs. All operators and mechanics should be trained. The owner is responsible for training the users. Only allow responsible adults, who are familiar with the instructions, to operate the unit. Never let children or untrained people operate or service the equipment. Local regulations may restrict the age of the operator. The owner/user can prevent and is responsible for accidents or injuries occurring to themselves, other people or property. PREPARATION Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Use only accessories and attachments approved by the manufacturer. Wear appropriate clothing including safety shoes, safety glasses and ear protection. Long hair, loose clothing or jewelry may get tangled in moving parts. Inspect the area where the equipment is to be used and remove all objects such as rocks, toys and wire, which can be thrown by the machine. Use extra care when handling gasoline and other fuels. They are flammable and vapors are explosive. a) Use only an approved container. b) Never remove fuel cap or add fuel with the engine running. Allow engine to cool before refueling. Do not smoke. c) Never refuel or drain the machine indoors. Check that operator s presence controls, safety switches and shields are attached and functioning properly. Do not operate unless they are functioning properly. OPERATION Never run an engine in an enclosed area. Operate only in the daylight or with good artificial light, keeping away from holes and hidden hazards. Be sure of your footing while using pedestrian controlled equipment, especially when backing up. Walk, don t run. Do not operate in reverse unless absolutely necessary. Always look down and behind before and while traveling in reverse. Be aware of the blower discharge direction and do not point it at anyone. Do not operate the blower without deflectors in place. Never leave a running unit unattended. Always stop engine before leaving unit. Never operate with guards not securely in place. Be sure all safety features are attached, adjusted properly and functioning properly. Never operate with the discharge deflectors removed or altered. Do not change the engine governor setting or over speed the engine. Stop on level ground, shut off engine before leaving the operator s position for any reason. Stop equipment and inspect impeller blades after striking objects or abnormal vibration occurs. Make necessary repairs before resuming operations. Keep hands and feet away intake and discharge areas. Keep pets and bystanders away. Do not operate the unit while under the influence of alcohol or drugs. Use caution when crossing roads and sidewalks. Stop engine if not blowing. Use care when loading or unloading the machine into a trailer or truck. Use care when approaching blind corners, shrubs, trees or other objects that may obscure vision. SLOPE OPERATION Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope, or if you feel uneasy on it, do not drive on it. Do Blow across the face of slopes; never up and down. Remove obstacles such as rocks, tree limbs, etc.

4 2 safety rules regarding outdoor power equipment (cont.) Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles. Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction. Do Not Do not start or stop on a slope. If tires lose traction, proceed slowly straight down the slope. Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible. Do not use near drop-offs, ditches, or embankments. The operator could lose footing or balance or blower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in. Do not operate on slopes with wet grass. Reduced footing or traction could cause sliding. Do not use on excessively steep slopes. CHILDREN Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the unit and its activity. Never assume that children will remain where you last saw them. Keep children out of the blowing area and under the watchful care of another responsible adult. Be alert and turn unit off if children enter the area. Before and during reverse operation, look behind and down for small children. Never allow children to operate the unit. Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. EMISSIONS Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth defects, or other reproductive harm. Look for the relevant Emissions Durability Period and Air Index information on the engine emissions label. MAINTENANCE AND STORAGE Always observe safe refueling and fuel handling practices when refueling the unit after transportation or storage. Always follow the engine manual instructions for storage preparations before storing the unit for both short and long term periods. Always follow the engine manual instructions for proper start-up procedures when returning the unit to service. Never store the machine or fuel container inside where there is an open flame, such as in a water heater. Allow unit to cool before storing. Shut off fuel while storing or transporting. Do not store fuel near flames or drain indoors. Keep all hardware, especially impeller bolt, tight and keep all parts in good working condition. Replace all worn or damaged decals. Never tamper with safety devices. Check their proper operation regularly. Clean leaves and debris from mufflers and engine to prevent fires. Clean up oil or fuel spillage. Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting. Never make adjustments or repairs with the engine running unless specified otherwise. Park machine on level ground. Never allow untrained personnel to service machine. Carefully release pressure from components with stored energy. (e.g. springs) Only replace impellers. Never straighten or weld them. Keep hands and feet away from moving parts. Frequently check components and replace with manufacturer s recommended parts, when necessary. Use only factory authorized replacement parts when making repairs. Always comply with factory specifications on all settings and adjustments. Only authorized service locations should be utilized for major service and repair requirements. Never attempt to make major repairs on this unit unless you have been properly trained. Improper service procedures can result in hazardous operation, equipment damage and voiding of manufacturer s warranty.

6 4 unit operation STARTING THE ENGINE IMPORTANT NOTE: The procedures outlined within this section are general guidelines, and are in no way meant to replace or supercede engine manufacturer s operating instructions. In order to obtain optimum performance from your engine, refer to your engine manual. WARNING! IMPELLER IS MOUNTED DIRECTLY TO ENGINE SHAFT STARTING ENGINE WILL RESULT IN IMMEDIATE HIGH-VELOCITY DISCHARGE. TO AVOID INJURY OR DAMAGE, BE SURE DISCHARGE IS POINTED AWAY FROM PEOPLE, PETS AND PROPERTY WHEN STARTING. BEFORE STARTING ENGINE: Be sure that the unit is completely assembled, all fasteners are tightened securely, and all safety guards and components are in place. Be sure to check engine s oil and fuel levels* and add as needed. (See engine manual for recommended oil and gasoline specifications.) Never check the engine while it is running or while you are smoking. Check only when engine is cold. * All machines are shipped without oil or fuel unless otherwise noted. Be sure that fuel valve is set to open position. OPEN CLOSED TO START ENGINE: Move choke control located on engine to the closed ON position to start a cold engine. (Briggs engine shown design and location may vary with engine. Refer to engine manual.) CHOKED Move engine speed control located on upper handle to the fast Rabbit position. FAST

7 4 unit operation (cont.) STARTING THE ENGINE (cont.) Bracing unit with one hand on the upper handle and one foot on the right rear tire, grasp recoil handle and pull briskly. You may have to pull several times before engine starts. (If engine fails to start within a reasonable amount of time, discontinue and check engine manual for further instructions.) Note: Do not allow recoil rope to snap back into recoil; damage to the rope or recoil could result. After engine starts, move engine speed control to approximately half and move choke control to open OFF position. PULL BRISKLY TO SHUT ENGINE DOWN: Move engine speed control to the slow Turttle position. Allow engine to idle for 2-3 minutes before shutting down. Move engine speed control to STOP position. Turn fuel valve to closed position. IMPORTANT NOTE: If you experience problems with your engine that cannot be satisfactorily resolved by following the instructions contained within the engine manual, contact your local engine dealer, or call the toll-free service number listed in the repair section of the engine manual. All engine service, warranty or otherwise, is required to be performed by a manufacturer-authorized service center. The equipment manufacturer is neither authorized nor responsible for any type of warranty engine service, nor is it equipped to perform any such service. BLOWER OPERATION DANGER! DO NOT PASS BY OR STAND ON THE AIR DISCHARGE SIDE OF ANY LEAF BLOWER WITH THE ENGINE RUNNING. HIGH VELOCITY DISCHARGE CAN EASILY TURN HARMLESS DEBRIS INTO FLYING PROJECTILES. DANGER! NEVER INSERT ANY BODY PART OR FOREIGN OBJECT INTO ANY OPENING WHILE UNIT IS RUNNING. SERIOUS INJURY OR DEATH CAN RESULT.

8 4 unit operation (cont.) GENERAL RULES TO OBSERVE BEFORE AND DURING OPERATION: Inspect your unit before each and every use. Check for worn, bent or broken components, loose fasteners, low or flat tires, etc., and repair or replace prior to operation. DO NOT OPERATE A DEFECTIVE UNIT SERIOUS INJURY OR DEATH CAN RESULT. Clear the entire work area of all debris that could cause damage to or become entangled in the unit. Rocks and large branches can wedge themselves between the impeller and housing, causing equipment damage or personal injury. If in doubt, remove it. Do not start unit until you are ready to begin blowing, and promptly shut off unit as soon as operation is complete. Keep hands, feet and clothing away from rotating parts. Never place your feet or hands in path of discharge. Use proper discretion in selecting your debris removal pattern, especially on uneven terrain. Avoid steep hills, especially if surface is wet. Do not travel straight down slopes exceeding 14 degrees. If tires begin to slip when climbing a slope, the grade is too steep for safe operation. Angle the unit to a less steep slope until tires stop slipping and traction is regained. Be keenly aware of your surroundings while operating unit children and pets can pop out of nowhere. Learn to listen to your machine being aware of what a well-running unit sounds like can alert you to a potential problem. A straining engine or clanging impeller means that trouble is almost sure to follow. TO BLOW DEBRIS OUT TOWARD FRONT OF UNIT: Open the forward air deflector door, mounted on the front of the discharge end of the blower, by pushing the control lever to the front of the machine. This feature is ideal for such things as blowing debris from a wall or fence. Adjust engine speed to increase or decrease air discharge rate. OPEN TO BLOW DEBRIS OUT TOWARD SIDE OF UNIT: Adjust the side air deflector, mounted on the discharge end of the blower, by means of the 5/16 x 5/8 hex bolts on either end of the deflector. NOTE: SHUT UNIT DOWN BEFORE ADJUSTING SIDE DEFLECTOR. This will permit you to direct the air at the angle you desire for a specific application. Adjust engine speed to increase or decrease air discharge rate. By changing the deflector angle and the engine speed, you can move debris into a neat row easily and rapidly.

9 5 maintenance GENERAL: Follow implicitly the engine manufacturer s recommendations for maintenance. Always keep your machine clean - especially the engine. Check all adjustments periodically. Also, periodically check that all fasteners are secure. Never make any adjustments to the unit until the engine is off and the spark plug wire is disconnected. If carburetor adjustment is necessary, stand to one side and keep feet and hands in the clear while making adjustments. Keep engine free of accumulations of grass, leaves or excessive grease. An accumulation of these combustible materials may result in a fire. Store gasoline in a safe and approved container in a cool, dry place. Keep the unit and any fuel containers in locked storage to prevent children from playing and/or tampering with them. Do not store gasoline powered equipment or fuel containers in a basement or any closed area where heating or heat appliances or open pilot lights are present, unless the fuel is completely drained from the power equipment and the fuel containers. LUBRICATION: The pneumatic tires on your blower contain bearings that should be lubricated on a weekly basis using a high-performance, automotive quality grease to ensure long life and minimal wear. TROUBLESHOOTING: UNIT WILL NOT START: Check fuel and oil levels. Check to make sure choke is set when engine is cold, off when hot. Check throttle for proper operation. Check intake baffle for jammed debris or accumulation of debris. If condition persists, contact dealer. UNIT STALLS: Check fuel and oil levels. Check intake baffle for jammed debris or accumulation of debris. If condition persists, contact dealer.

10 5 maintenance (cont.) EXCESSIVE NOISE OR VIBRATION: Check to make sure all fasteners are tightened securely. Remove intake baffle and visually inspect impeller for broken, bent, or cracked blades; also make sure impeller hub is securely tightened onto engine shaft bolts should be torqued to 15 ft/lbs each. Pull recoil and check for bent engine shaft. Contact dealer for repair or replacement if necessary. Do not attempt to repair a damaged impeller or bent engine shaft. Serious injury or equipment damage may result. BEFORE REMOVING INTAKE BAFFLE, OR ANY OTHER COMPONENT, STOP ENGINE AND DISCONNECT SPARK PLUG WIRE TO PREVENT INADVERTENT STARTING OF UNIT. UNIT DOES NOT TRAVEL STRAIGHT: Check tire pressure 24 psi rear. Adjust as needed. Check camber on front wheel, adjust as needed see Front Wheel Camber Adjustment. Make sure wheels are lubricated see Lubrication. ADJUSTMENTS: BEFORE MAKING ANY ADJUSTMENTS, STOP ENGINE AND DISCONNECT SPARK PLUG WIRE TO PREVENT INADVERTENT STARTING OF UNIT. THROTTLE CABLE ADJUSTMENT: Correct cable adjustment allows for full range of movement of throttle body on engine in conjunction with throttle control on handle. To adjust, loosen cable clip screw on engine, then slide cable housing in or out in approximately 1/8-1/4 increments. Retighten screw, recheck, readjust as needed. LOOSEN SCREW MOVE CABLE

11 5 maintenance (cont.) ADJUSTMENTS (cont.): BEFORE MAKING ANY ADJUSTMENTS, STOP ENGINE AND DISCONNECT SPARK PLUG WIRE TO PREVENT INADVERTENT STARTING OF UNIT. FRONT WHEEL CAMBER ADJUSTMENT: Correct camber adjustment will place the front axle at 0 degrees, or parallel with level ground, and the wheel at 90 degrees or perpendicular with level ground. Adjust by loosening the three mounting bolts and placing a square aside the wheel and adjusting until square sits flat on ground and touches upper and lower points of tire, then retightening bolts.
